Answer:
There are about 2 more students in each class at Oak Middle School than at Poplar Middle School.
Step-by-step explanation:
The rest of the question is the attached figure.
It is required to compare between the mean number of students for the data in the plots.
The mean is sum of all data divided by the number of data.
The data set of Poplar Middle School:
20,20,20,21,21,21,21,21,22,22,22,22,22,22,22,23,23,23,23,24
So, The mean = 435/20 = 21.75
<u>The data set of Oak Middle School:</u>
20,21,21,22,22,23,23,23,23,24,24,24,25,25,26,26,27,27,28,29
So, The mean = 483/20 = 24.15
The difference in mean = 24.15 - 21.75 = 2.4
So, the correct statement is:
There are about 2 more students in each class at Oak Middle School than at Poplar Middle School.
